Wind Energy

Let us develop your product! From the moment your idea is born all the way to production!

As providers of development services, we design pitch and energy storage systems for wind turbines and develop complete control systems and drives, electronic components, firmware and suitable housing. Our stable and mature development processes enable the highest quality and on-schedule delivery of your development results.

Engineering Services


  • Our team has more than 10 years of experience in developing efficient and highly robust, reliable system solutions in pitch systems for onshore and offshore wind turbines.
  • We design, develop and verify functionally safe drive systems and subsystem components.
  • We specify, design and develop electrical energy storage and uninterruptible power supplies (UPS) according to your requirements.
  • For type tests and series tests in production we develop and supply test benches.

Engineering Services

  • Based on pre-concept studies and feasibility studies, such as statistical load simulation and analysis, we define system requirements.
  • At all levels of system development, we develop architectures, detailed specifications, specifications and test specifications.
  • We simulate electric drive systems such as pitch systems with MATLAB® Simulink® and in DNV GL Bladed, thus optimizing control structures.
  • We develop, verify and qualify the performance and safety features of electromechanical systems in our in-house laboratory and accompany the certification.

Series production and the product life cycle

  • Once development has been completed, we expertly adjust your production - or that of an EMS - and support your product throughout its entire life cycle.
  • We take the pressure off your team by providing competent support for your successful brand-name products.
  • In the event of component discontinuations, we will help you revise your systems and products.
